NOVEL PYRAZOLE DERIVATIVE
Technical Field
The present invention relates to a novel compound; a
tau protein (hereinafter also referred to as tau)
aggregation inhibitor, a P-secretase inhibitor, and a p-
amyloid protein (hereinafter also referred to as AP)
aggregation inhibitor using the same; and a novel pyrazole
derivative useful for the prevention or treatment of
diseases such as dementia and Alzheimer's disease and a
pharmaceutical composition containing the same.
Background Art
Senile dementia has become a serious medical and social
problem along with the rapid aging of society in recent
years and the development of effective anti-dementia drugs
has been greatly desired. There are already very many
studies on Alzheimer's disease but the cause of the disease
has not been clearly defined. Drugs such as
acetylcholinesterase inhibitors including donepezil
(Aricept (registered trademark)), galantamine (Reminyl) and
rivastigmine (Exelon/Rivastach), and NMDA receptor
antagonists including memantine hydrochloride (Memary) have
been used as Alzheimer's therapeutic drugs. These drugs
are very useful as symptomatic therapy but are not drugs
for fundamental treatment.
Alzheimer's disease is considered to be caused by
aggregation of AP, aggregation of tau, and the like. Hence,
a substance that inhibits aggregation of these proteins
CA 02888140 2015-04-10
2
could be used as a fundamental therapeutic drug for
Alzheimer's disease.
Yang et al. have reported that curcumin has an AP
aggregation inhibitory activity, a disaggregation activity
on AP aggregate, and the like (Non Patent Literature 1).
The inventors of the present invention have revealed that
curcumin and its derivatives have an inhibitory activity
against secretase, which is involved in the generation of
AP (Patent Literature 1 and 2). Narlawar et al. have
synthesized curcumin derivatives by replacing the 1,3-
dicarbonyl moiety with a pyrazole ring and reported that
these compounds have a tau aggregation inhibitory activity
(Non Patent Literature 2).

Summary of Invention
Technical Problem
As described in the above literature, a curcumin
derivative can be a promising candidate for a fundamental
CA 02888140 2015-04-10

therapeutic drug for Alzheimer's disease. Under this
technical background, an object of the present invention is
thus to provide a novel therapeutic means for Alzheimer's
disease.
Solution to Problem
The inventors succeeded in creating a novel compound
based on technical ideas that are distinct from those
forming the basis of known compounds and found that the
compound has an excellent pharmacological activity. The
inventors further conducted extensive studies to complete
the present invention.
That is, as a result of the extensive investigations to
solve the above problems, the inventors succeeded in
synthesizing a curcumin derivative by replacing the 1,3-
dicarbonyl moiety of curcumin with a pyrazole ring and
replacing at least one of the 4-hydroxy-3-methoxyphenyl
groups at both ends with a substituent, and found that this
novel compound has a potent tau aggregation inhibitory
activity. The inventors also found that this derivative
has a high brain penetration and also possesses a p-
secretase inhibitory activity and an AP aggregation
inhibitory activity.
A curcumin derivative in which the 1,3-dicarbonyl
moiety of curcumin is replaced with a pyrazole ring is
described in Non Patent Literature 2 etc. A curcumin
derivative in which one of the 4-hydroxy-3-methoxyphenyl
groups at both ends of curcumin is replaced with a
substituent is described in Patent Literature 1 and 2, etc.
CA 02888140 2015-04-10

However, the derivative of the present invention which has
a pyrazole ring and in which at least one of the 4-hydroxy-
3-methoxyphenyl groups at both ends is replaced with a
substituent is a novel compound having a chemical structure
that is unique to the present invention and distinct from
those of compounds disclosed in known literature.
The tau aggregation inhibitory activity of a curcumin
derivative is described in Non Patent Literature 2. In
this literature, the nitrogen atom at position 1 of the
pyrazole ring is replaced with various groups, and the tau
aggregation inhibitory activities of the derivatives
significantly vary with the groups introduced into the ring.
However, no modification was made to the benzene rings at
both ends and thus all the synthesized derivatives have the
4-hydroxy-3-methoxyphenyl groups as curcumin does.
Therefore, the person skilled in the art who has read Non
Patent Literature 2 is expected to consider that the group
introduced into the pyrazole ring plays an important role
for the tau aggregation inhibitory activity and that the 4-
hydroxy-3-methoxyphenyl groups at both ends are irrelevant
to the tau aggregation inhibitory activity. Thus the
person skilled in the art would not attempt to replace the
4-hydroxy-3-methoxyphenyl groups with a substituent.
That is, the present invention relates to the following.

Pharmacological test example 1: Determination of tau
aggregation inhibitory activity
Recombinant three-repeat microtubule-binding domain
(3R-MBD) of tau protein was expressed in E. coli and was
purified and used for the experiment. The purified tau
solution was diluted with a 50 mM Tris-HC1 buffer (pH 7.6)
to a final concentration of 10 M. The test compounds were
prepared using dimethylsulfoxide (hereinafter also referred
to as DMSO) at 20-fold of their final concentrations and
added to the tau solution so that the DMSO concentration
would be 5%. To this solution, heparin was added so that
the final concentration would be 10 M and the plate was
left to stand at 37 C for 16 hours. Thioflavin T was added
CA 02888140 2015-04-10
119
to the plate so that the concentration would be 10 M and
the fluorescence intensity was measured with a fluorescence
plate reader (PerkinElmer, Inc.)(excitation wavelength: 440
nm; fluorescence wavelength: 486 nm).
The final concentration of each compound at the time of
measurement was set at 0.1, 0.3, 1, 3, and 10 M. The
sample to which only DMSO was added was used as a negative
control and its fluorescence intensity was taken as 0%
inhibitory activity to determine the 50% inhibitory
concentration (IC50) of each compound. The results are
shown in Table 39. Table 39 also shows the calculated
maximum inhibition (%) of the compounds that exhibited
particularly high maximum inhibition () at the
concentrations used for the determination of the tau
aggregation inhibitory activity.

As is apparent from Table 39, some of the compounds of
the present invention exhibited a particularly high tau
CA 02888140 2015-04-10
120
aggregation inhibitory activity. The compounds that
exhibited high maximum inhibition are expected to have
improved therapeutic effects and are thus more preferred.
Pharmacological test example 2: Determination of p-
secretase inhibitory activity
The P-secretase inhibitory activity was measured with
BACE-1 FRET assay Kit (Invitrogen). The test compounds
were prepared using DMSO at 30-fold of their final
concentrations and added to an assay buffer so that the
DMSO concentration would be 10%. To each of the solutions,
equal volumes of a human recombinant P-secretase (1 U/mL)
and a fluorescent substrate peptide (750 nM), each
dissolved in an assay buffer, were added and the solutions
were left to stand for 1 hour. The fluorescence intensity
was measured with a fluorescence plate reader (excitation
wavelength: 545 nm; fluorescence wavelength: 590 nm).
The final concentration of each compound at the time of
measurement was set at 0.1, 0.3, 1, 3, and 10 M, at 0.3, 1,
3, 10, and 30 M, or at 1, 3, 10, 30, and 100 M. The
sample to which only DMSO was added was used as a negative
control and its fluorescence intensity was taken as 0%
inhibitory activity to determine the 50% inhibitory
concentration (ICH) of each compound for the evaluation of
P-secretase inhibitory activity of each compound. The
fluorescent substrate peptide had the amino acid sequence
of Ser-Glu-Val-Asn-Leu-Asp-Ala-Glu-Lys-Arg, in which the
Ser residue at position 1 was labeled with a fluorescent
CA 02888140 2015-04-10
121
donor (Cy3) and the Lys at position 9 was labeled with a
fluorescence quencher (Cy5Q).
The compounds of the present invention exhibited a high
P-secretase inhibitory activity.
Pharmacological test example 3: Determination of AP
aggregation inhibitory activity
AP 1-42 (Peptide Institute, Inc.) was dissolved in 0.1%
ammonia water so that the concentration would be 0.5 mM,
and then diluted with PBS to 20 M. The test compounds
were prepared using DMSO at 100-fold of their final
concentrations and then diluted with PBS so that the DMSO
concentration would be 2%. The AP solution and each of the
test compound solutions were mixed at an equivalent ratio
and the mixtures were left to stand at 37 C for 24 hours.
To each of the mixtures, an equal volume of a thioflavin T
solution adjusted with a 100 mM Tris-glycine buffer (pH
8.5) to 6 M was added. The fluorescence intensity was
measured with a fluorescence plate reader (excitation
wavelength: 440 nm; fluorescence wavelength: 486 nm).
The final concentration of each compound at the time of
measurement was set at 0.1, 0.3, 1, 3, and 10 m or at 2, 4,
8, and 16 M. The sample to which only DMSO was added was
used as a negative control and its fluorescence intensity
was taken as 0% inhibitory activity. With the use of the
fluorescence intensity of the control taken as 0%
inhibitory activity, the 50% inhibitory concentration
(IC50) of each compound was calculated to evaluate the AP
aggregation inhibitory activity of each compound.

Pharmacological test example 4: Concentration measurement
in brain after oral administration
Each of the compounds of the present invention shown in
Tables 40 and 41 and the compound of Example 2 of JP 2012-
229208 A was orally administered to ICR mice (male, 7 weeks
old) in a single dose of 5 mg/kg. At 3, 6 and 9 hours
after the administration, 1, 3, 6 and 9 hours after the
administration, or 1, 3, 6, 9 and 24 hours after the
administration, the mice were subjected to perfusion by
infusing physiological saline into the heart under
inhalational anesthesia with isoflurane, and the whole
brain was harvested. Physiological saline was added to the
harvested brain in an amount equal to twice the wet weight
of the brain and the brain was homogenized. Then, an equal
volume of methanol was added thereto, and the mixture was
deproteinized. The concentration of each compound in the
sample was measured by LC/MS/MS. The test results are
shown in Tables 40 and 41.
